Is that a good price? Secondly, the reason as to why I want to purchase more memory is because I want to run multiple desktops, with applications like iTunes, Logic Pro, and Lightroom being run at the same time. I also don't want to have to close applications, as I prefer to leave them running all the time.

Are you sure it is upgradable to 16GB? All specs from here show that it has an 8GB limit.

And It can read 1333 or 1600. So you'd be safe in speed, but as for the quantity, you are over the limit.

Yeah I've read about this too, although I have read posts where users have gotten 16GB of memory to work. Well I guess maybe after what +abysal said I will get the 8GB sticks. They're $50.00 cheaper + I won't have to deal with the event my MacBook does not accept 16GB.

Thanks guys.

And one other question, maybe directed towards Mindovermaster, but will a 1600MHZ stick have a noticeable impact on the performance of my machine? or should I just stick with the 1333MHZ
